L

and a modification thereof, which my invention The i "proved clamp of my inventionisused may assumein practice. v and assembled "on the cable or cables adaptedto I the r w n s: I n be clamped in thefollowing'manner. The clamp Figure 1 is alongitudinal sectional view through is usually applied adjacent the end "of a cable C ,the improved clamp of my invention showing a after the same has been looped about a'member cable clamped therein; I v to which the cable is adapted to be attached, as Figure 2 is a sectional view taken on lineII-II 33 shown in Figure 1cf the drawings. The cable C of Figure 1'; i I is flrst threaded through the opening 3 'inI' the Figure 3 is a side elevational view of a modified space on one slide of the wedge 6 between the side form of clamp of my invention, showing a pluthereof and the sidewall of the opening. The rality of cables clamped therein; and V cable is then looped aroundthe member to which Figure 4 is a sectional view taken on line io itis adaptedt'o be connected and is then passed IVIV of Figure 3. b ackjthrough' the opening 3 in the space on. the Referring more particularly to the drawings, opposite'side o f the wedge 6 so as to provide an the'improved clamp of my invention, as shown assembly, as shownin Figural of the drawin s.

in Figures 1 and 2, comprises a body member 2 d The nut then tightened so as to move the having a wedge-shaped opening 3 arranged therewedgej into the openin 3 relative tothe body through and extending longitudinally thereof so member2. Upon such movement of the wedge 6 as to provide opposed angularly arranged o'rconand after the nut has beensuflici'ently tightened, verging side walls 4 in the opening, Thewall of it will be seen that the metallic linings Bjon the the opening 3 is lined preferably with a plastic sides": 1 of the Wedge} will cooperate with the metallic material, such as lead, babbitt; or the lining 5' on thesides 4 of the opening 3 so as to like as'at 5; a securelyholdand clamp those portions 'of the There.is arranged in the larger endof the opencable disposed therebetweeng' v d f ring 3 of the body member 2 centrally and axially In Figures '3; and 4 of the drawings, there is thereof, a'wedge-shaped member 35 having'sides I a' slightniddification oi the improved "or edges 1 which conform'to the 'angularity of the clamp ofmy invention.- In" this construction,

there is provided a frusto-izonical-shaped body member I'I having a irusto-conical-shaped opening I8 arranged therethrough and extending lonbitt, and the like, similar to the liners 8 in the preferred embodiment.

There is arranged in the larger end of the;

opening I8 in the body member II, a frustb conical wedge-shaped member 2| which is positioned axially of the opening l8 with the sides therefrom spaced therefrom, as s hown in Figure 4. In the outer periphery of the wedge member ZI, there is arranged a plurality of spaced apart;

semi-cylindrical grooves 22 similar in size and numberto the grooves I9 in the body member I] withone positioned'directly opposite one of the grooves I9 in thebody member so as to provide aplurality of concentrically arranged cylindrical-shaped spaces therebetween. eachlof the semi-cylindrical grooves 22 -of the wedge member 2|, there is arranged a semi-cylindrical liner, or insert 23" similar to the inserts or liners 28.. There is arranged axially of the opening I8 in the body member I! and extending thereinto, an eyebolt 24 with the eye portion 25 thereof as before, preferably pivotallyconnected to the body member by means of a. transversely extending pin or rivet 26 arranged in a hole, extending through the body member in a manner similar to that of the preferred embodiment. The threaded portion of the eyebolt 2 I extends through an opening 29 arranged axially through the wedge 2|, and there is arranged on'theouter end of the threaded portion beyond the wedge 2 I, preferably a washer 21 and a nut 28. I

Thi'smodified form of clampis designed primarily for clamping, two or more ropes with the clamp usuallyapplied adjacent the end of the cables after the samehave been looped about a member, as shown in Figure 3 of the drawings, in a manner similar to thepreferred form. In this latter construction, each of the. ca tt'iles is threaded. through one of the cylindrical spaces :formed by one of the semi-cylindricalgrooves I9 in the side of the opening I8 and the respective semi-cylindrical groove 22 in the, periphery of the wedge 2|. and back through a' similar space on the opposite side of the wedge 2i. After the cables have been properly threaded through the clamp and thesame has been positioned at, the desired point on the cables, the nut 28 is tight- .e'ned so as to force the wedge member 2| into the opening I8.

Upon movement offthewe'dge 2I and after the nut 28has been suflici'entlytightened, it will be seen that the portions of each .of the cables C positioned in the spaces between the wedge 2| and the sides of the openings I8 of the body member I I will be securely gripped and clamped due to the cooperation of the liners 23 of thewedge 2| with the liners carried by the body member IT. 1 ,1

, As a;result of my invention, it will be seen that there is provided aclamp which consists of the I minimum number of inexpensive parts which can be easily and conveniently manufactured and assembled. Also, it will be seen that by providing liners for the gripping surfaces of the clamp, that the cables will be securely clamped and held flrmly. in position whereby any slippage of the that, these embodiments ,are; merely for the purpose. of illustration and description and that various other forms may be devised within the scope of my invention, as defined in the appende claims. 1 I claim:
